No, this isn’t an advertisement for the new “Call of Duty” game. Watch what keeps our enemy up at night as a SEAL Delivery Vehicle (SDV) goes underwater to insert SEALs and their equipment onto an objective.

The SDV is used for secret missions into denied-access areas. It can carry up to six combat-equipped SEALs. The SDV’s chamber is flooded, then the men utilize an internal compressed-air supply, along with their personal SCUBA equipment, to remain stealthy.
